Ridstar E26 Review: One Motor, 28 MPH, 749 Wh

26 × 4.0 fat tires on a chromoly steel frame · one motor Ridstar rates "1000W Brushless Motor" · 48V 15.6Ah, 748.8 Wh by arithmetic · 28 kg, riders 5'3" to 6'3" · our E26 listing sold out at $631.35 · verified November 3, 2026

Quick Answer — On November 3, 2026, our E26 listing read sold out at $631.35, and ridstar.com sold its US variant at $1,089.00. This is Ridstar's one-motor E26, on 26 × 4.0 tires, for riders 5'3" to 6'3". Modeled on level pavement without pedaling, its pack takes a 180 lb rider 45 miles at a steady 15 mph.

For a US address that day, ridstar.com's E26 listing offered the E26 in stock to US buyers at $1,089.00, against a "Regular price" of $1,399.00. ridstar.net's E26 listing, the only variant it offers, showed sold out at $549.00.

Ridstar sells a second bike under almost the same name, the two-motor E26 Pro, and the identity section shows how to tell the pair apart before you read any figure. For a bike you can order today, the verdict points to four we have in stock.

Ridstar's record is the first thing to know. The Consumer Product Safety Commission's warning 26-337 says the Q20 and Q20 Pro's "batteries and wires can ignite". Its warning 26-584 says a Q20 or Q20 Lite front wheel "can detach without warning", and both tell owners to stop riding those bikes.

The E26 appears in neither warning, and on November 3, 2026, the CPSC's recall list carried no recall from Ridstar at all. Britain's report 2506-0011 names the E26 Pro and its charger, and Ridstar's parts store sells the E26's charger on the same listing as the E26 Pro's; the record section quotes all of it.

How we verified this Ridstar E26 review

The E26's figures on this page come from Ridstar's two E26 listings, on ridstar.net and ridstar.com, loaded for US delivery on November 3, 2026; their bullets matched our copies of August 26, 2026, word for word. We opened every photograph at its full size, and every computed range and fit figure comes with its working in the section that uses it.

The same day we read the CPSC record, two federal dockets, the federal statute, the California, Oregon, District of Columbia, Montana and Rhode Island codes this page quotes, and our own stock; Ridstar's dealers were read on October 28, 2026. Part of our e-bike reviews.

The E26's figures, as Ridstar prints them

Ridstar's two E26 listings agree on the motor's bullet, the tires and the gears, and part ways on range, warranty and, inside one listing, on the motor and the pack. Our reading of each row comes first and the stores' own wording after it, printed once where the two stores agree.

The first photograph on both of Ridstar's E26 listings, ridstar.net's and ridstar.com's, and the second on ours.

Sources for every row: on ridstar.net's E26 listing, the bullets, the Technical Details tab and the gallery; on ridstar.com's, the bullets, the slider, the design sections and the gallery; both loaded for a US address on November 3, 2026. Watt-hours are Ridstar's volts multiplied by its amp-hours, and 61.7 lb is its 28 kg converted.

Four rows decide most of what follows. State e-bike definitions read the motor and top-speed rows, so they settle the class section; the battery row drives the range section; and the fit section sets the rider-height row against a survey of 6,068 Army bodies.

Two rows need a second look. The suspension row's rear shock appears in Ridstar's text and in none of its E26 photographs, as the frame section shows at full size, and the 2,000 W and 14 Ah figures sit in ridstar.net's Technical Details tab, below bullets that print 1,000 W and 15.6 Ah.

Neither Ridstar store prints a maximum load for the E26, and neither do its dealers ridstar.eu and ridstar-ebike.com. So the weight rows end at a 260 lb rider, a limit this page chose because Ridstar prints no load figure.

Which E26 is this? The one-motor bike, not the Pro

The E26 is a gray steel fat-tire bike with one motor in the rear wheel, a battery on the down tube, a suspension fork, a rear rack, fenders and seven gears; the E26 Pro is a different machine with two motors and a rear shock. Ridstar's own page names blur the pair, so check the motor count and the pack size before you trust any listing, ours included.

The E26 column from ridstar.net and ridstar.com; the E26 Pro column from ridstar.net's E26Pro listing and ridstar.com's, including the E26 Pro's dimension drawing, read October 28, 2026; the four listings read again for US delivery on November 3, 2026. Watt-hours are volts times amp-hours.

The mix-up starts in a web address. ridstar.com's E26 page sits at an address ending "e26-dual-motor-1000w-48v-23ah-battery", while the page itself is titled "Ridstar E Bike E26 1000W 48V 15AH Battery" and its slider prints "1000W" and "48V/15.6AH". Its first two photographs are the same files as ridstar.net's E26 photographs, compared pixel by pixel across 26 galleries.

So the photographs and the figures on that page are the one-motor E26's; only the address borrows the Pro's dual motor and 23 Ah. Owners trip on the name too. The thread that opens Endless-Sphere's discussion of the E26 Pro begins "I bought a Ridstar E26", about a bike whose owner writes that "it claims 1000 watts on each motor".

Ridstar's second E26 photograph, on ridstar.net and ridstar.com alike. The motor sits in the rear hub, inside the sprockets.

In a photograph the two machines part at the wheels and under the saddle. The E26 Pro's own drawing shows a motor in its front hub and a coil shock below its seat, on a black frame; the E26's studio photographs show a plain front hub with a disc, and a rear triangle with no shock, on a gray frame. A seller's picture of either feature on an "E26" is a picture of the Pro.

Which photographs show the E26

Every photograph on Ridstar's two E26 listings is an E26 photograph: none matched a picture on Ridstar's own E26 Pro, DC26, H26 Pro, MN26 or MN20 listings in the comparison. ridstar.net carries seven: the two studio views, two of the cockpit, the headlight, the taillight and a battery graphic. ridstar.com carries five: the same two studio views, two cockpit photographs of its own and a dimension drawing.

ridstar.net's battery graphic adds two lines to the text, "48V 15.6AH LARGE CAPACITY BATTERY" and "Max Range 25-70Miles". The dimension drawing on ridstar.com, labeled "SIZE", adds the lengths the fit section works from, in centimeters only.

The photographs also show what the text leaves out. A second black box sits on the top tube near the seat tube, and Ridstar's pages say nothing about it; the bullets' "48V 15.6AH Dual Battery" is the only hint, and no page explains whether "Dual" means two packs or one.

Who the E26 fits: a 5'3" to 6'3" window and a saddle range of 87 to 98 cm

Ridstar's highest saddle setting stops 98 cm (38.6 inches) above the ground, while the 109% rule puts the saddle top 38.8 inches above the pedal axle for the median 6'1" body in the US Army's ANSUR II survey, so at the tall end of Ridstar's 5'3" to 6'3" window the seat post runs out before the formula does.

ridstar.com prints the window on its slider, "Recommended Height 5'3" -6'3"", and its "SIZE" drawing gives the saddle top two heights from the ground, "87CM" at the low setting and "98CM" at a raised, ghosted one. ridstar.net prints no window and no seat figure.

The "SIZE" drawing from ridstar.com's E26 listing, shown whole and evenly scaled. Its figures are in centimeters only; 87 cm is 34.25 inches and 98 cm is 38.58 inches.

Three steps take you from your body to a saddle height:

1. For your inseam, stand shoeless against a wall, lift a hardcover book spine-up between your legs until it meets resistance, and read the height of its top edge from the floor.
2. Go to your height's row in the saddle table, make sure your inseam falls inside its band, and take the saddle-top height it gives above the pedal axle.
3. On delivery day, set the seat with the heel check, then watch the bend of your knee at the bottom of the stroke for the first few rides.

What seat height does the Ridstar E26 need?

The table's middle column applies 109% of inseam from the pedal axle to the saddle top, the method Peveler et al. (2005) compared with the heel check. The outer columns come from Ferrer-Roca et al. (2012), whose review puts the range at 106% to 109% and whose own equation gives 108.6% to 110.4%.

Each band holds the middle 90% of inseams at one height among the 6,068 bodies in the US Army's ANSUR II survey, and no row stands on fewer than 30 of them.

Formula saddle heights for the E26, each from the median inseam of its height row. The 109% column is Peveler et al.'s and the 106% and 110.4% columns Ferrer-Roca et al.'s; LeMond's 88.3% counts from the crank axle, and no E26 page prints a crank length, so it has no column.

Ridstar measures both settings from the ground, so the saddle top at the low setting sits less than 87 cm (34.25 inches) from the pedal by however high the pedal rides. A rider whose 106% figure is 34.25 inches or more, an inseam of 32.31 inches or longer, can be sure the post goes low enough; for a shorter leg the printed figures cannot answer either way.

At the top the same arithmetic runs the other way. A saddle 38.58 inches from the ground is less than that from the pedal, so if your 109% figure is above 38.58 inches, an inseam over 35.4 inches, you cannot reach the formula's height at the highest setting.

Each count is over the survey's bodies at that height, against Ridstar's 87 cm and 98 cm saddle heights. A rider is counted only where a printed figure proves the answer on its own; for the rest of the row the answer depends on the pedal height, which no E26 page prints.

The squeeze on the E26 is at the top. At 6'1", the post's highest setting falls short of the 109% height for 55 riders in 100, at 6'2" for 74 and at 6'3" for 86, all inside Ridstar's own window. The 6'3" median rider would need about 39.9 inches above the pedal, against a saddle that tops out at 38.6 inches above the ground.

At the bottom, the figures prove the lowest setting low enough for 94 riders in 100 at 5'10" and for just 5 in 100 at 5'4"; for the others below 5'10" the answer turns on the pedal height. Where Ridstar's window and the survey part ways, at either end, both stay on this page for you to weigh.

Can you put a foot down on the E26 at a stop?

No standover height is printed for the E26, and the "SIZE" drawing marks none. On the E26's step-over frame the top tube falls from the head tube toward the seat tube, and Ridstar prints no clearance over it, so ask your seller for that figure before you buy.

The survey can at least size the leg that must clear it: by ANSUR II, the median inseam is 30.1 inches at 5'3" and 32.6 inches at 5'8".

The E26's figures from ridstar.com's drawing and slider, the DK400's from Smartravel's own page; the drawing read October 28, 2026, both pages again on November 3, 2026.

A shorter rider who wants a seat figure in hand has one on the DK400: Smartravel answers "What is the seat height on the DK400?" with "The seat height is 33 inches", without saying where it is measured from. The E26's lowest printed setting is 87 cm, 34.25 inches, from the ground; the DK400 rides on 20-inch fat tires.

Will you sit stretched or cramped on the E26?

Ridstar prints neither a reach nor a grip position for the E26, so the lean from upright is not computed here.

The drawing gives one cockpit figure, the bar top at "115CM", about 45.3 inches above the ground, and ridstar.com's text adds "height-adjustable handlebars" without a range. If your arms are short for your height, ask your seller for the bar's height at its lowest setting and its distance behind the head tube.

How much weight goes through your wrists on the E26?

Ridstar publishes no grip position for the E26, so this page does not work out what share of your weight the bars carry. For scale only, Carahalios (2015) measured road racers on the hoods putting about 15% of their body weight on the stem; Ridstar's drawing puts the E26's bar top above its saddle at both settings, and no E26 figure is drawn from that study.

How do you set the E26's saddle when it arrives?

One E26 frame covers Ridstar's whole 5'3" to 6'3" window, so your fit is made at the seat post the day the bike arrives. Start with the heel check: sit on the saddle, bring one crank to the bottom of its turn in line with the seat tube, and rest your heel on that pedal, where the leg should be straight.

If the knee will not straighten with your heel on the pedal, the saddle is too low; if your hips roll to keep the heel on it, it is too high.

Then ride and look at your knee each time a crank reaches the bottom. For that bend, Peveler, Pounders and Bishop (2007) cite 25 to 35 degrees, a range they draw from earlier cycling studies.

Ferrer-Roca et al. (2012) found 30 to 40 degrees best. A bend near 30 degrees meets both.

The fit arithmetic, step by step

Three fractions of inseam, 106%, 109% and 110.4%, fix the saddle top's height above the pedal axle for each ANSUR II body in the model. Worked for a rider 68 inches tall: in the survey, that height's median inseam is 32.64 inches, which at 109% puts the saddle top 35.6 inches over the pedal axle; at 106% it would sit at 34.6, and at 110.4% at 36.0.

Hamley and Thomas get the credit for the 109% figure in Peveler et al. (2005). LeMond's method gave 109.2 ± 0.9% of inseam when that team measured it the same way, from the pedal, in their 19 trained cyclists.

LeMond's own 88.3% is taken from the crank axle, so checking it against the 109% needs a crank length, and no E26 page prints one; Limitations records that. The drawing's lengths were also checked against each other at one scale, and they did not agree closely enough to measure anything else off it, so the window is Ridstar's, the two saddle heights are Ridstar's, and the counts are the survey's.

The motor: 1,000 W in the rear hub, 2,000 W in one tab

Both Ridstar stores print "1000W Brushless Motor" for the E26, and ridstar.com's slider repeats "1000W" above "POWERFUL MOTOR"; ridstar.net's Technical Details tab, on the same page as its bullet, says "Motor 2000W". No Ridstar page names a motor maker, a torque figure or a controller current for the E26, and none says whether 1,000 W is a continuous rating or a peak.

The motor sits in the rear wheel. The drive-side photograph shows a broad hub inside the seven sprockets, and Ridstar's parts store sells a "Rear hub contains motor" listing and a separate "Ridstar Motor" listing, each with a "US / E26" option, at $379.00 and $209.00 on ridstar.net on November 3, 2026.

Ridstar's dealers add two more readings. ridstar-ebike.com lists the E26 at "1500W Brushless Motor" in its bullets and "1000W (Peak 1500W)" in its comparison table, and ridstar.eu prints "Power: 1000W". The tables on this page run the motor at 1,000 W, and the formula subsection reruns them at 2,000 W.

Ridstar's top speed is "28+++MPH Max Speed" in the bullets and "Max Speed 28 MPH" on ridstar.com's slider. The dealer ridstar-ebike.com prints "30MPH Max Speed", and ridstar.eu's image "45KM/H Max Speed", about 28 mph. If 28 mph is how fast the motor spins with nothing to push, the model has a 180 lb rider settle at 25.0 mph on flat pavement without pedaling.

The range model's own top speeds for a 180 lb rider on the 61.7 lb bike, with the motor's no-load speed set from Ridstar's 28 mph. At the dealer's 30 mph instead, the flat row rises to 26.3 mph and the 4% row and steeper do not change.

The steeper rows assume the controller lets the pack deliver whatever current the climb needs. On a 15% grade at 10 mph the model draws 47.6 A from a 48 V pack, and Ridstar prints no controller rating for the E26, so on long, steep hills expect to ride slower than those rows.

For pedaling, ridstar.com's display paragraph says the E26 "is also equipped with a 5-speed mode, which offers more options than the normal 3-speed mode", and the display in Ridstar's cockpit photograph reads "PAS 1". Neither store says what speed each level holds, so the range tables are set by your speed and your effort, never by a level number.

Battery: 48V 15.6Ah in the bullets, 14Ah in one tab

Both Ridstar stores print "48V 15.6AH Dual Battery", which is 748.8 Wh by Ridstar's own volts times amp-hours; ridstar.net's Technical Details tab also prints "48V 14AH", 672 Wh, and "Wattage 672 kWh" (sic). ridstar.net's battery graphic agrees with the bullets: "48V 15.6AH LARGE CAPACITY BATTERY", "Detachable" and "Lockable".

The down-tube battery and the top-tube box, cropped from Ridstar's drive-side photograph. Ridstar labels neither in its text.

ridstar.com describes "a uniquely designed battery that is detachable and portable". No E26 page says what "Dual" means in "Dual Battery", or whether the box on the top tube holds cells. Read the label on any pack you are offered: 15.6 Ah or 14 Ah decides which row of the pack table is yours.

A spare pack is sold for the E26 on a listing titled for other bikes. ridstar.net's "Ridstar Q20/DC26/H20 48V 20AH 15AH Removable Electric E-Bike Battery" offers a "US / E26" option at $429.00, in stock on November 3, 2026, without giving that option's capacity, and YVY's matching listing offers "US / E26" at the same $429.00.

No E26 page prints a charging time, and Ridstar's charger listing prints no output for the E26. That listing, "Ridstar Charger", is headed "Selling chargers for Q20 Lite 48V15AH(2A),Q20 48V20AH(3A),Q20 PRO,H20,H20 PRO and other electric bicycle models", and sells "US / E26" and "US / E26 PRO" options at $69.00 each, so ask your seller which charger ships with the bike and what it puts out.

Refilling an empty 748.8 Wh pack costs about 14 cents at the US residential average for August 2026, 18.16 cents per kWh. The figure leaves out the charger's own losses.

Range on the 15.6 Ah pack: 45 miles at 15 mph without pedaling

At a steady 15 mph on flat pavement, the range model carries a 180 lb rider 45 miles on the E26's full 748.8 Wh without pedaling, 34 miles if you hold a quarter of the pack back, and 70 miles with 75 W of easy pedaling. The computed figures below come from a physics model built on Ridstar's published numbers and published studies; the subsections show what changes them.

To get your own figure from the tables, take three steps:

1. Start from your usual speed and how hard you pedal, and find that pair in the speed and effort tables.
2. Take the climbs, the load and the temperature from the hill, weight and cold rows.
3. Then plan from the reserve column, the one that leaves the last quarter of the pack alone.

How far does the E26's 48V 15.6Ah pack go?

Speed is the biggest lever: on flat pavement without pedaling, a 180 lb rider gets 63 miles at 10 mph and 22 at 25 mph from the same full pack. Speed is the costliest setting on the bars, because air drag climbs with the square of speed.

Miles on the full 748.8 Wh and with a quarter kept back, for a 180 lb rider on the 61.7 lb E26, steady speed, flat pavement, motor only, 77 °F, no wind. No 28 mph row appears: on the flat the model tops out at a steady 25.0 mph.

Ridstar's Technical Details tab prints the pack as 14 Ah. If that is the pack you are offered, the 15 mph row falls from 45 miles to 40.

The same rides on both printed packs: 48V 15.6Ah (748.8 Wh) and 48V 14Ah (672 Wh), full and with a quarter kept back, 180 lb rider, flat pavement, motor only.

Your legs move these numbers more than anything except speed. At 15 mph, 75 W of easy pedaling takes the full-pack figure from 45 miles to 70.

Full-pack miles at four steady speeds on flat pavement for a 180 lb rider: the motor alone, and with 75 W and 150 W from the rider's legs.

What do the E26's seven gears change?

On a hub-drive bike like the E26 the gears change your cadence, never the motor's: the motor turns with the wheel whatever sprocket the chain is on. What the gears change is how much you can add, and your watts come straight off what the motor has to supply.

Watt-hours drawn from the pack per mile for a 180 lb rider: on the flat at 15 and 20 mph, and at 12 mph on 4% and 8% grades, with the motor alone and with 75 W or 150 W from the legs.

With the motor switched off, the same 7 speeds still carry you: the model puts a 180 lb rider at about 9.2 mph on the flat on 75 W of pedaling and about 13.3 mph on 150 W, on a 61.7 lb bike.

Does going uphill drain the E26's pack faster?

Yes, and fast: a 4% grade at 10 mph takes 40 Wh a mile, more than three times the 11.8 Wh the same speed costs on the flat, which leaves a 180 lb rider about 19 miles, motor only. On 8% the figure is 10 miles.

Watt-hours per mile and full-pack miles at a steady 10 mph on a sustained grade, 180 lb rider, motor only and with 75 W of easy pedaling.

Counted by height climbed, every 1,000 ft up costs the pack about 135 Wh on a 4% grade at 10 mph on the motor alone, and about 174 Wh on 10%; easy pedaling brings those to about 119 Wh and 154 Wh. At the wheel, about 91 Wh of each 1,000 ft goes into raising a 180 lb rider and the 61.7 lb bike; heat in the motor and the pack takes the remainder.

On the motor alone, every 1,390 ft or so of 4% climbing uses a quarter of the 748.8 Wh pack, the share the reserve column holds back. On hilly routes, put your legs to work on the climbs and plan from the reserve column.

Does rider weight affect the E26's range?

On the flat, weight matters less than speed: an extra 80 lb, from 180 lb to 260 lb, takes a 15 mph ride from 45 miles to 40 on the motor alone. On a climb it matters far more, because every pound has to be lifted.

Full-pack miles for the rider and anything you carry together, motor only: on the flat at 15 and 20 mph, and on an 8% climb at 10 mph. The rows stop at 260 lb because no Ridstar store and neither of its dealers prints a maximum load for the E26.

Ridstar prints no load limit for the E26, so the weight rows are not a promise that the bike carries 260 lb. Ask your seller for the figure in writing before you load yourself and your cargo near it.

Does cold weather drain the E26's battery?

For a 180 lb rider, the 15 mph ride without pedaling that reaches 45 miles at 77 °F falls to 36 miles at 32 °F, within a bracket of 32 to 38, and to 32 at 14 °F, within 16 to 32. No E26 page names the cells, so the energy column borrows the LG HG2, an 18650 cell whose output at each temperature is published.

Temperature by temperature: what fraction of its 77 °F energy the pack still delivers, and how many motor-only miles that gives a 180 lb rider at 15 mph on the flat. Brackets from freezing down span the published cell measurements.

Warmth works the other way. At 95 °F the cells keep 99% of their energy and the tires roll more freely, so the ride reaches 47 miles, beyond the 77 °F row.

The model lowers rolling resistance by about 0.9% for each degree Celsius of warmth, and holds it flat below 41 °F. Bicycle Rolling Resistance's temperature test found six road tires rolled 17.6% easier on average as their surface warmed from 20 °C to 40 °C, and Rothhämel's (2023) climate-chamber measurements point to a similar rate.

A pack kept indoors and carried out warm will beat its row on a cold morning, because each row assumes the cells sit at the air's temperature. Ridstar's own line for the E26 is "Downtown around, rocky roads, sandy beaches, snowy suburbs, and even urban jungles".

Do the E26's fat tires cut range?

On pavement the tire alone moves the 15 mph ride from 42 to 52 miles: 52 on the easiest-rolling of ten drum-measured fat tires, 42 on the heaviest, and the tables use their median, 45. The E26's sidewall reads CHAOYANG in Ridstar's "SIZE" drawing, and no E26 page names the tread or gives a pressure.

No Chaoyang tire is among those ten, all of them 26 × 4.0 tires like the E26's, so the model runs on their median rolling coefficient, 0.0105, with 0.0070, the easiest roller, and 0.0126, the heaviest knobby casing, as the outer limits.

Full-pack miles at 15 and 20 mph on the flat, motor only, for a 180 lb rider, with the rolling coefficient set to the ten tires' lowest, median and highest. Sand and snow have no rows, because the model holds rolling data for pavement only.

How you sit is the other big loss. Tengattini and Bigazzi (2018) measured 0.640 m² of drag area for upright cruiser riders, the posture the model assumes, and 0.603 m² for riders in a mountain-bike crouch, which stretches the 15 mph ride to 47 miles.

The front wheel, cropped from Ridstar's lead E26 photograph. The heaviest-rolling tire, a knobby one, sets the upper row, since deep knobs drag on pavement where smooth rubber rolls.

Is the E26's 45 to 60 miles real?

Ridstar prints the E26's range three ways, "Max Range 60 Miles" on ridstar.net, "Max Range 45 Miles" on ridstar.com, and "Max Range 25-70Miles" on a ridstar.net graphic, and never with a speed, a load or an effort beside it. Read backward, the model turns each distance into the steady speed that would produce it.

For a 180 lb rider on flat pavement, a full pack lasts 45 miles at a steady 15.1 mph on the motor alone, 60 miles at 10.9 mph, and 70 miles at 8.4 mph without pedaling or at 15.1 mph with easy pedaling. Ridstar's low figure, 25 miles, matches riding flat out near 23 mph.

Read across: for each range Ridstar prints, the steady speed at which a full 748.8 Wh pack lasts that far on flat pavement, carrying a 180 lb rider on the 61.7 lb bike, at three efforts (motor only, 75 W of easy pedaling, 150 W of steady pedaling). The distances come from ridstar.net's bullets and battery graphic and ridstar.com's bullets and slider, read November 3, 2026.

So ridstar.com's 45 miles is a 15 mph ride with the motor doing the work, and ridstar.net's 60 needs either a slow 11 mph or some pedaling. For your own figure, start from the speed table and its reserve column.

The range arithmetic, one ride at a time

The force against the bike is rolling resistance plus air drag plus, on a hill, gravity; that force times speed is the power at the wheel, and dividing by the drivetrain's, the motor's and the pack's efficiencies gives what the cells must deliver. The equation comes from Martin and colleagues' (1998), and every input in the table below names its one source.

Every run of the model writes out this table: Ridstar's own numbers, the inputs measured in published studies, the comparable motor and its brackets, and the constants of physics, each source repeated under References.

One ride worked through, end to end: the 61.7 lb E26, a 180 lb rider, a steady 15 mph on flat pavement, motor only.

The wheel needs 190.2 W, 76.0 W against rolling resistance and 114.2 W against the air. The motor runs at about 79% efficiency there and draws 240.4 W at the battery's terminals; the cells supply 248.8 W, the difference being the pack's own losses.

At 15 mph, 248.8 W works out to 16.6 Wh a mile, so the full 748.8 Wh lasts 45.1 miles, or 33.9 with a quarter held back. At 18.16 cents per kWh, 1,000 such miles cost about $3.01 in electricity.

Two checks hold the model to its sources. Against the example worked in Appendix I of Martin and colleagues' paper, it gives the same 45.7 W of rolling and potential power and 158.8 W of aerodynamic power that the authors print. The second is the comparable motor's rated point, where it gives the 80% efficiency Bafang's workbook sets as its floor.

Because the motor curve is borrowed from a comparable motor, the model is run three more ways, and the 15 mph flat figure holds between 42 and 49 miles across all four. At a 750 W rating it gives 45 miles, at Ridstar's tabbed 2,000 W it gives 42, and at 82% efficiency 49; on the 8% climb at 10 mph the four give 9 to 11 miles.

All four are computations from the model, and every table on this page uses the 1,000 W case.

Brakes, lights and the display

Ridstar prints disc brakes for the E26 without saying what kind: "Dual Brakes" in both stores' bullets, "disc brake" in ridstar.net's Technical Details and "dual disc brakes" in ridstar.com's design text. Neither store's E26 page gives the brakes' maker, their rotor size, cable or hydraulic actuation, or any motor cut-off at the levers.

The parts store does: ridstar.net's "Ridstar Electric bikes brake set" listing sells "US / Left front brake / E26" and "US / Right rear brake / E26" at $90.00 each, and its brake pads listing a "US / E26" pair at $35.00. Ask your seller which brakes your bike carries, because a cable caliper needs adjusting as its pads wear, and on a 61.7 lb bike at 28 mph that adjustment matters.

Ridstar's dealer ridstar-ebike.com, in its table of the two E26s, lists the E26's brakes as "Dual Disc Brakes" and the E26 Pro's as "Dual Hydraulic Brakes".

Ridstar's cockpit photograph from ridstar.net's E26 listing, shown whole and evenly scaled. The display shows kilometers per hour in this picture; no E26 page says whether it can be set to miles.

For light, ridstar.com lists "transmitted LED headlights and taillights" and calls the rear lamp "ultra-bright rear-mounted taillights", and ridstar.net's Technical Details include "Headlight" among the features. Ridstar's photographs show a round headlight behind a grille and a red rear lamp under the rack; no page gives a lumen figure.

The headlight, from ridstar.net's E26 gallery, shown whole at its native size.

The taillight, from the same gallery, shown whole at its native size.

ridstar.com calls the display a "SMART LCD METER" with "power display, speedometer, mileage statistics", and Ridstar's photograph of it shows an energy bar, the speed, the assist level and an odometer.

Frame, suspension, tires, gears and what comes in the box

Ridstar's text gives the E26 suspension at both ends, "Suspension Type Front，Rear" on ridstar.net and a "Rear Shock Absorber" on ridstar.com, yet every Ridstar photograph of the whole bike shows a suspension fork and a rear triangle with no shock in it. Read at full size, the seat stays run straight from the rear axle to the seat tube, with no shock or pivot between the frame and the rear wheel.

The rear of the frame, cropped from Ridstar's lead E26 photograph. The same rigid rear triangle appears in Ridstar's drive-side photograph and its "SIZE" drawing, and on ridstar.eu's three E26 images.

ridstar.com's longer paragraph reads "Ridstar E26 uses a 700Lbs shock absorber and dual front fork shock absorber system", and the dealer ridstar-ebike.com's table gives "Font and Rear, Dual Shock Absorber" (sic). Both stay on this page beside the photographs; if a rear shock decides your purchase, have your seller send a photograph of the bike you will receive, taken from the side.

The frame is steel, "Frame Material Chromoly Steel" in ridstar.net's Technical Details, over "26×4 Inch Fat Bike Tires" on spoked wheels. The gears are seven at the rear, "7-speed Shimano Mechanical Shifting" in both stores' bullets, and the shifter in Ridstar's photograph is a Shimano thumb lever with a gear window; Ridstar does not name the derailleur.

The rack and fenders are fitted in every photograph of the whole bike. ridstar.net's Technical Details list what is in the carton: "1* Fat tire electric bike,1* Battery,1* Charger,1* Front and rear fenders,1* Tool kit,1* Bike Pump", in a package of "148*29*81cm" weighing "35kg".

Above the price, ridstar.net's E26 page carries this line: "Note: Front tires must be securely installed, Self-modification may posesafety risks." (sic). On delivery day, hold the front wheel to that note, and if you are unsure it is fastened properly, let a bike shop check it before the first ride.

The Mercer fit test

Our reviews set the bike against the Mercers, a cast of seven riders, and here each of them meets the E26 in turn.

Three readings sit in each row: where the member stands in Ridstar's 5'3" to 6'3" window, the 109% saddle height of the median ANSUR II body of that height, and what Ridstar's 87 cm and 98 cm saddle settings show for riders that tall. Read the row nearest your own height.

The Mercers' ages are on their family page; the heights are the ones we give each member. The saddle figures are the fit section's own, 109% of each height's median ANSUR II inseam above the pedal axle, and the counts are read off that section's second table.

Jack, at 6'1", is the Mercer the E26 serves least well, though he sits inside Ridstar's window: for most riders his height the post's highest setting stops short of the formula. Ruth, Maya and Dana face the opposite question at the bottom of the post, and the printed figures cannot answer it for most riders their height.

A taller rider can ask a seller what a longer seat post would take; a shorter one needs the pedal height, which no E26 page prints. For riders from 5'4" up who want a seat figure in hand, Smartravel's DK400 page prints "Recommended rider height is 5'4" ~ 7'" and "The seat height is 33 inches".

For Cole, at 16, and Ivy, at 12, no. ridstar.net's E26 page sets the buyer's age at 18 and asks for an adult alongside a younger rider: "E-Bikes Are Not for Sale to Persons Under the Age of 18. Underage riders MUST be accompanied by parents or adults when riding."

Ridden on a throttle at Ridstar's 28 mph, the E26 falls outside every state's e-bike definition, which puts a teenage rider on whatever motor vehicle their state's code calls it. Our kids and teens guide matches four age bands, from 5 to 16 and over, to bikes we sell and sets out the state age rules that go with them.

Is the Ridstar E26 UL certified?

Neither Ridstar store claims a UL certification for the E26: no bullet, Technical Details row, design section, structured-data field or E26 photograph mentions UL, a standard or a certificate. That is a fact about Ridstar's pages, and a certificate could still exist; without a holder's name and a file number there is nothing for you to look up.

A 748.8 Wh pack is reason enough to want proof: before paying, get the certificate holder and the file number from your seller in writing and look them up with UL. UL Solutions names the two standards involved: UL 2849, "the Standard for Electrical Systems for eBikes", and "UL 2271, the Standard for Batteries for Use in Light Electric Vehicle Applications".

UL says UL 2849 works "by examining the electrical drive train, battery, and charger system combinations in e-bikes", so a certificate should name the combination it covers. Of the bikes this page points you to, Smartravel prints "Safety Certified in Accordance with UL 2849" for the DK400, and Freesky prints "UL2849 Certified by TÜV" and "UL2271 Certified by TÜV" for the M-410.

ridstar.net's footer, the same on the E26 page as across that store, carries an "Our Qualifications" menu whose three entries, "US trademark", "CE trademark" and "European trademark", open PDFs. The US and EU files, US Reg. No. 6,936,242 of December 27, 2022, and EU No 018609888 of March 16, 2022, record "Huizhoushi Xingqishi Sports Goods Co., Ltd." as the Ridstar name's owner.

The third, under "CE trademark", is a test report to EN 15194:2017, number ATS240329142LR, dated April 2, 2024, for a "Cargo electric bicycle" with the model reference "FM-002, CDDA20" and a "Maximum power measurement" of "250W". None of the three names the E26, and none is from UL.

Has the Ridstar E26 been recalled?

No. Read on November 3, 2026, the CPSC's recall database listed no recall from Ridstar or its maker and no bicycle record bearing the E26's name in any spelling. Both of the Commission's stop-use warnings about Ridstar concern Q20-line bikes, three models in all, with fire named for the Q20 and Q20 Pro and a detaching front wheel for the Q20 and Q20 Lite.

On that day the database held 10,070 records, the latest from October 29, 2026, and the names Ridstar, YVY, HK Ridstar and Xingqishi occur in none of them. The two records that do contain "E26" are a 2018 lamp-socket recall, for "a medium (E26) size lamp socket", and a 2014 light-bulb recall naming an "E26 Base"; neither concerns a bicycle.

The recall feed carried 40 items from October 1 to October 29, none of them Ridstar's, and the Commission's warning list names the brand in 2 of its 382 rows, the two warnings below. A recall can follow after this page is written, so search the recall database for "Ridstar" on the day you order.

The maker's record

None of the records below names the E26: the two CPSC stop-use warnings, the two lawsuits and the British border rejection. Two links run to it: Ridstar's parts store sells E26 parts through listings shared with the warned Q20s, and the British report names the E26 Pro, the E26's two-motor namesake, and its charger.

Below, each finding appears in the words of its source, whether the regulator, the court or the owner.

The two rows exactly as they stood on the Commission's warning list on November 3, 2026, read from cpsc.gov.

Both releases name one maker, the Chinese firm Huizhou Xingqishi Sporting Goods Co., Ltd., and both report how it dealt with the Commission. The fire warning, from March, records that the firm "has refused to agree to an acceptable recall" and gives its reply in full: "The company objects to this press release". Three months later, the crash warning found it "unresponsive to CPSC's requests for information about these products or a recall".

Every one of the 11 ridstar.net parts listings that sells an E26 option also sells an option for a Q20-family bike. On November 3, 2026, ridstar.net's catalog feed held 83 products, and the 11 with an E26 option include the rear hub motor, the controller, the throttle, the display, the charger, the spare battery and the front fork; 8 of the 11 also carry an E26 Pro option.

The front fork listing prices "US / E26" at $159.00 and "US / Q20" at $189.00; the front-wheel nut kit listing carries an E26 Pro option and no E26 option. Whether any part the E26 shares a listing with is the Q20's own, no Ridstar page says.

The Q20's front wheel is the part the June warning says "can detach without warning". Get the E26's front axle and its fastening hardware named in writing by whoever sells it, and hold the bike to ridstar.net's own note, "Front tires must be securely installed".

Owners who need to check a Ridstar against the warnings start where the March release points them, the model number. Amazon.com, Ridstar.net and Walmart.com are its sellers, AliExpress.us joins them in the June release, and redtailebikes.com appears in neither.

Britain's case concerns the E26 Pro and its charger. The Office for Product Safety and Standards report 2506-0011, of June 19, 2025, rates the risk "Serious" for three Ridstar e-bikes, the Q20-Plus, the Q20-Mini and the E26 Pro, and their chargers.

Its findings are "poor quality soldering" and a transformer short of "the minimum requirements for creepage and clearance distances", and it warns that "If the product was left plugged in overnight, the charger and plug could overheat, causing a fire". Its record of action is "The import has been rejected at the border."

The E26 is not named in it. Ridstar's charger listing, though, sells "US / E26" and "US / E26 PRO" side by side at $69.00 and prints no output for either, so neither Ridstar's listing nor Britain's report tells you whether the E26's charger is the unit Britain examined. Whatever charger your E26 comes with, unplug it when the pack is full instead of leaving it on overnight.

Two lawsuits, both about a front wheel

In two filed lawsuits a Ridstar loses its front wheel, the wheel "detached" in one and the tire "became removed from the bike" in the other, and in both the defendant is the retailer that sold the bike, not Ridstar. The Oregon case, Cunanan v. Amazon.com Services LLC, No. 3:26-cv-00692, concerns a "Ridstar Q20"; when we checked the docket on November 3, 2026, nothing had been filed since a stipulated protective order of July 8, 2026.

The Florida case, L.E. v. Walmart Inc., No. 9:26-cv-81045 in the Southern District of Florida, was brought on behalf of a minor and alleges that "the front wheel unexpectedly detached during normal operation". Its newest entry is an "Order on Motion to Dismiss" of October 23, 2026, whose text the free docket does not show.

The Florida complaint names no model. Walmart's listing title for the bike opens "Ridstar Electric Bike, Peak 1500W30MPH,48V". The rest reads "15.6Ah Electric Bicycle, Full Suspension Mountain Bike UL2849", and the order is dated August 29, 2025.

Several of those words appear in E26 text, the 48V 15.6Ah pack and the front-and-rear suspension on Ridstar's pages, and the "Peak 1500W" and "30MPH" on the dealer ridstar-ebike.com's E26 page; other Ridstar listings print 15.6 Ah too, and no E26 page claims UL 2849. The complaint does not say which bike it was, and its claims are allegations.

What owners have written about the E26

Neither Ridstar E26 page carried an owner review on November 3, 2026: ridstar.com's review widget shows no count, and ridstar.net's page has no review data. The owner posts that name an "E26" elsewhere mostly concern the E26 Pro.

The best-known, the Endless-Sphere thread "Ridstar E26 pro review and opinions", opens with an owner writing "I bought a Ridstar E26" about a bike that "claims 1000 watts on each motor", the two-motor Pro.

In March 2025 a reader in the same thread wrote "I just got the Ridstar E26 and the throttle is not working" without saying which E26, and the thread's opening poster answered that the throttle works only in "one of the PAS 1-5 settings, on 0 it will not work". If you are offered an owner's account of "the E26", check its motor count before you weigh it.

Who would you be buying from?

Hung Hom's Man Yue Street is the address ridstar.net's company page gives, for a firm called "HK RIDSTAR TRADE LIMITED". The US and EU trademarks belong to "Huizhoushi Xingqishi Sports Goods Co., Ltd.", and the CPSC names Huizhou Xingqishi Sporting Goods Co., Ltd. as the warned Q20s' maker.

YVY sells E26 parts as well: its battery listing offers a "US / E26" option at $429.00, the same price as Ridstar's. How YVY connects to Ridstar is set out in our YVY profile, and our Ridstar profile covers the same ground from Ridstar's side.

Which Ridstar store would you be buying from?

ridstar.net's official statement separates its own store from all the others: "Except ridstar.net, other similar websites are our dealers". Buyers from anywhere else are cut off in the same statement: Ridstar "will not provide any after-sales service to customers who purchase ridstar products from other places".

ridstar.com's E26 listing narrows its own cover the same way: "The Ridstar Warranty Policy is only available to customers ordering from ridstar.com." The store you order from is the one that answers to you, and on November 3, 2026, ridstar.com was the one Ridstar store taking US orders for the E26.

Two other sites using the Ridstar name, ridssttaar.it.com and ridstaearshop.it.com, listed a "Ridstar E Bike E26 1000W Motor 48V 20AH Battery" in stock on October 28, 2026, at $164.70 against a struck $549.00, with ridstar.net's E26 text copied word for word.

Any site trading as Ridstar should tell you, in writing and before you pay, whose warranty you are buying and who will service the bike; measure its answer against ridstar.net's statement.

Ridstar's warranty reads three ways for the E26. ridstar.net's Technical Details print "1 Year Warranty" and a banner "One year warranty on all products". A part qualifies if it "proves defective because of hardware malfunction under regular use and maintenance", by its warranty page. For such a part, "Ridstar dealers or Ridstar authorized partners will repair or replace, at no charge".

ridstar.com's listing offers a "Hassle-Free 2-Year Warranty", and the dealer ridstar.eu prints "Warranty 12 months". Which applies to your order is your seller's to answer in writing; Buying it from us sets out ours.

Where the E26 sits among Ridstar's bikes

The E26's closest relative is the E26 Pro, which shares its name and its 26 × 4.0 tires and differs in motors, pack and frame; the identity section compares them figure by figure. Nineteen more Ridstar reviews are live here, every one built on Ridstar's own published figures:

• Ridstar E26 Pro review: the two-motor namesake, and the bike Britain's report 2506-0011 names with its charger.

For bikes from other makers, read on in our e-bike reviews; Ridstar, the business, has a profile of its own.

1,000 W at 28 mph: outside every US e-bike definition on a throttle

Measured against the low-speed electric bicycle of 15 U.S.C. § 2085(b), the E26 passes on "fully operable pedals" and fails both of the statute's limits. The statute asks for "an electric motor of less than 750 watts (1 h.p.)" and a top speed on the motor alone that "is less than 20 mph".

Ridstar's 1,000 W is a third above the federal motor line, and its 28 mph is 8 mph past the speed line; the 2,000 W in ridstar.net's Technical Details would be well past both.

Sources: Ridstar's two E26 listings; the federal statute at govinfo; and California's section from the Legislative Counsel's bulk files of the code as the Legislature shows it; all read on November 3, 2026.

California's three classes all stop at a motor that "does not exceed 750 watts of power", under § 312.5(a), so the E26's 1,000 W keeps it out of every one. The speed rules would exclude it as well: class 2 cuts the throttle off at 20 mph, and class 3 gets to 28 mph only with the rider pedaling and a speedometer fitted.

Read against California's code as it stands through December 31, 2026, the E26's printed figures fit § 406(a), the "motorized bicycle" or "moped". It wants "fully operative pedals for propulsion by human power" and a motor "that produces less than 4 gross brake horsepower".

The E26's 1,000 W is about 1.3 horsepower, and the 2,000 W in the Technical Details about 2.7, both under § 406's 4. Ridstar's 28 mph is under the section's speed line, "not more than 30 miles per hour on level ground", and so is the model's own top speed for a 180 lb rider on the flat, 25.0 mph.

The section also asks for "an automatic transmission", and the E26's pages print "7-speed Shimano Mechanical Shifting" and never use that term.

California from January 1, 2027

SB 1167, Chapter 846, Statutes of 2026, starts on January 1, 2027, and its new § 312.5(c) names the vehicles that are not electric bicycles. Two entries on that list catch the E26: "motor power of more than 750 watts", and, if the motor drives it unaided, "capable of attaining a speed greater than 20 miles per hour on motor power alone".

The same bill rewrites § 406 from that date: the moped keeps the 30 mph ceiling, caps the motor below "4 gross brake horsepower (3,000 watts)", and is "designed for highway use". From that date a moped "shall comply with all applicable federal motor vehicle safety standards". It must also "have a 17-digit vehicle identification number and a safety certification label".

You will find no vehicle identification number, federal safety standard or certification label on either E26 listing, on ridstar.net or on ridstar.com.

Before you ride an E26 in California, ask the DMV which vehicle class it falls into and what that class requires of you. Our California page lays out both sections and the code around them.

State by state

Of the 50 states and the District of Columbia, every code but Alaska's and Kentucky's defines an e-bike, 49 in all. Forty-four cap the motor in watts, every one at 750, with wording that runs from "less than" to "not more than"; four, the District, Montana, New Jersey and Oregon, print no power figure, and Rhode Island caps it at "not more than two (2) (S.A.E.) horsepower", about 1,491 W.

On a throttle, at 1,000 W and Ridstar's 28 mph, the E26 fits not one of those 49 definitions. Even a 750 W motor printed at 28 mph on a throttle fits none, because every definition that allows a throttle stops it at 20 mph.

If the E26 has no throttle and assists only while you pedal, two definitions would take it at 1,000 W and 28 mph: Oregon's, which caps no power, and Rhode Island's. No E26 page settles the throttle question, so take Ridstar's own throttle listing as the working answer until your seller tells you in writing what your bike has.

Cap the same 1,000 W throttle bike at 20 mph and four definitions take it: the District's, Montana's, Oregon's and Rhode Island's. No 20 mph setting appears on either Ridstar store's E26 page, and ridstar.net's page adds the warning "Non-professionals please do not adjust the controller circuit！！！".

The bikes this page routes you to all print a figure above 750 W: the RS-A08 II's title reads "Peak 1500W", the STORM's "1000W (Peak 1800W)", the DK400's "750W (sustained), 1000W (peak)", and the M-410 has two motors, so each raises the same class question.

For a bike inside a class, start with our 750W guide. Whatever you buy, check it against your own state's definition, quoted from the statute in our atlas of state e-bike laws.

Mountain roads, beaches and snow: who decides where it rides

Ridstar pitches the E26 for "Downtown around, rocky roads, sandy beaches, snowy suburbs, and even urban jungles", and calls it "a mountain electric bicycle designed for mountain riding", but whoever governs each of those places rules on whether a 1,000 W bike may enter. Trails that admit e-bikes by class have no class to admit the E26 under.

Equestrian, hiking and recreational trails are closed to a motorized bicycle under California's § 21207.5(a), and so is "a bicycle path or trail, bikeway, bicycle lane". Exceptions run to a path "within or adjacent to a roadway" and to one a local authority opens "by ordinance". An E26 that California treats as a § 406 motorized bicycle falls under that rule, so ask the agency in charge before you ride a path.

The quoted words are ridstar.net's Technical Details and ridstar.com's design text for the E26. Where an agency's posted rule and this table disagree, the posted rule wins; set its watt or speed limit beside Ridstar's 1,000 W and 28 mph.

36 CFR 261.2 makes the E26 a motor vehicle on National Forest land, because the term covers "any vehicle which is self-propelled" and excepts only rail vehicles and devices for people with impaired mobility.

On a unit whose designated roads, trails and areas are drawn on its motor vehicle use map, 36 CFR 261.13 makes it "prohibited to possess or operate a motor vehicle". Riding there is lawful only "in accordance with those designations". The penalty for that, set by 36 CFR 261.1b, can mean up to six months' imprisonment, a fine under 18 U.S.C. 3571, or both.

Before an E26 trip to a federal trailhead, read our public-land guide, which goes agency by agency through national parks and forests, Bureau of Land Management land, wildlife refuges and Army Corps of Engineers lakes.

Green flags / Red flags

Below are eight things that may draw you to the E26 and twelve questions to settle before you pay for one, each red flag ending in a next step, with us or on a bike we sell.

Green flags

• One 1,000 W motor in the rear hub of a full-size fat-tire bike. "1000W Brushless Motor" on both Ridstar stores, on 26 × 4.0 tires, with a 28 mph top speed; the motor section sets out what the model makes of it on each grade.
• 45 computed miles at 15 mph without pedaling. If you weigh 180 lb, the speed tables give you 45 miles from the full 748.8 Wh on flat pavement, 34 with a quarter kept back, and 70 with easy pedaling.
• About 14 cents a charge. Electricity is cheap here: about 14 cents fills the empty pack and about $3.01 covers 1,000 miles at 15 mph without pedaling, at the EIA's August 2026 residential average.
• Seven gears that still work with the motor off. On 150 W of your own steady pedaling, the model moves a 180 lb rider at about 13.3 mph on the flat, by the gear subsection.
• The lighter of the two E26s. Ridstar prints 28 kg, about 61.7 lb, for the E26 and "75LBS" for the E26 Pro, by the identity table.
• Rack, fenders and lights fitted in Ridstar's studio photographs. ridstar.net's carton list adds a tool kit and a pump, and ridstar.com lists "transmitted LED headlights and taillights", by the brakes and lights section.
• A steel frame. "Chromoly Steel" in ridstar.net's Technical Details, under the rack and the 26-inch wheels, by the frame section.
• A seat range that suits you if you stand about 5'8" to 6'0". For most surveyed riders in that span the printed settings reach the 109% height at both ends of the post, by the fit section.

Red flags

• Sold out here. Our listing read sold out at $631.35 on November 3, 2026, while ridstar.com sold the E26 at $1,089.00; you can order the RS-A08 II, a 26 × 4.0 bike with a shock at each end, today at $1,299; to hear if the E26 comes back, email us.
• A rear shock in the text that no photograph shows. Ask your seller for a side photograph of the bike you will get; the RS-A08 II is the bike here whose maker prints "a 1000-pound hydraulic rear suspension".
• Two motor ratings. "1000W" in the bullets and "Motor 2000W" in ridstar.net's Technical Details, so have your seller write down which it is, then read the class section.
• Two pack sizes. 15.6 Ah in the bullets and 14 Ah in the Technical Details; the pack table runs both, and the label on the pack you receive settles which one you have.
• No throttle named on its pages, and 28 mph. Ridstar sells an E26 throttle part, and on a throttle at 28 mph the E26 fits no state's e-bike definition; for a bike inside a class, start with our 750W guide.
• Disc brakes of no stated kind. If you want hydraulic discs on the same tire size, Samebike prints "Large 180mm hydraulic brakes" for the RS-A08 II, $1,299 here.
• No UL claim. Ridstar prints none for the E26, and the UL section lists what you should ask for; Freesky prints "UL2849 Certified by TÜV" for the M-410.
• Parts and a charger listing shared with warned and reported bikes. All 11 E26 parts listings also sell Q20 parts, and the charger sits beside the E26 Pro's; the record section lists what to have named in writing.
• Short of the formula at the top of its own window. If you stand 6'1" to 6'3", the highest setting falls short for most riders your height, by the fit section; our tall-rider guide sorts bikes we sell by height.
• Unproven at the bottom for shorter riders. If you are under 5'8", the printed settings prove the lowest seat for fewer than half; the DK400 prints "The seat height is 33 inches".
• No load limit. Neither Ridstar store nor its dealers print one; if you need a printed figure, the M-410 carries "Max Load 400 LBS", and our guide for heavier riders sets out more.
• Each Ridstar store backs only its own buyers, and the warranty reads one year or two. If you order from us, Buying it from us names who handles a fault.

Buy it if / Buy something else if

Buy it if you want a one-motor fat-tire bike on 26 × 4.0 tires with a steel frame, 748.8 Wh and a rack; you stand about 5'8" to 6'0"; your seller, a restocked store or ridstar.com, puts the motor rating, pack, brakes, charger and rear suspension in writing; and you can live with how your state classes a 1,000 W machine that reaches 28 mph.

Charging costs little: about $3.01 a year if you ride 1,000 miles on the flat at 15 mph, priced at the national residential rate for August 2026.

Buy something else if a rear shock decides it for you. The Samebike RS-A08 II read in stock here at $1,299 on November 3, 2026, and Samebike's page prints "an effective 100mm double-crown front fork and a 1000-pound hydraulic rear suspension", 180 mm hydraulic discs and a "48v, 17ah" pack on 26 × 4.0 tires. It costs $667.65 more than our E26 listing, and our RS-A08 II review works it through.

Buy something else if you want more range from one motor. The Samebike STORM carries a 960 Wh pack, a "30mm Distance traveled Rear Shock" and an 8-speed Shimano drivetrain on 26 × 4.0 tires, for $1,299 here.

Buy something else if the E26's price is the reason you came. The Smartravel DK400 is $665 here, prints "Dual Suspension", a "1000W Geared Hub Motor", "86 N·m torque" and "Recommended rider height is 5'4" ~ 7'", and rides on 20 × 4.0 tires in a moped-style frame.

Buy something else if you want printed certifications and a printed load limit. The Freesky M-410 is $1,299 here, with "UL2849 Certified by TÜV", "UL2271 Certified by TÜV" and "Max Load 400 LBS" on Freesky's page; it has two motors and a printed 34 mph top speed, so it is more machine than the E26.

Before you buy: the checklist

Settle these eight with your seller, then on delivery day, before you ride an E26 on a public road.

1. Your state's class for it. Find the class your state gives a 1,000 W bike at 28 mph in our state law atlas, and ride by that class's rules.
2. The motor rating and the throttle, in writing. 1,000 W or 2,000 W, and whether a throttle is fitted, decide the class section's answer for your bike.
3. The pack label. Ask for a photograph of it: 48V 15.6Ah is 748.8 Wh and 48V 14Ah is 672 Wh, and the pack table carries both.
4. A side photograph of your bike. It shows whether there is a shock between the frame and the rear wheel, which Ridstar's text and photographs disagree on.
5. The brakes. Find out whether the calipers are cable-pulled or hydraulic; cable brakes want their tension checked on the day your bike arrives and again after your first few rides.
6. The charger and the front-wheel parts. Have the charger's output and the front axle and its fasteners named in writing, and check your front wheel is tight before every ride, as Ridstar's own "Front tires must be securely installed" asks.
7. Your inseam against the seat post. Get the pedal's height above the ground and the seat post's length from your seller, then hold both against your saddle height in the fit section.
8. The weight on board. Ridstar prints no load limit for the E26, so look up your weight plus your cargo's in the weight rows.

Buying it from us

Our E26 listing read sold out at $631.35 on November 3, 2026, so it takes no orders; order the RS-A08 II, the STORM, the DK400 or the M-410 here instead, and these terms come with it. The policies below are ours to keep, and you can hold us to every one.

Read on November 3, 2026: our checkout with the RS-A08 II in the cart, and our refund policy, shipping policy, contact page and terms of service.

A change of mind has a short window under our refund policy: 72 hours (3 days) from delivery, for a bike still unopened in its factory-sealed packaging, with a 15% restocking fee and the return shipping on you, and a 3% transaction fee on any canceled order.

For a US address, ridstar.com had the E26 at $1,089.00 on November 3, 2026, beside a "Regular price" of $1,399.00. Read its terms beside ours before you choose a store.

We wrote our column from our own policies; the ridstar.com column quotes its E26 listing as it loaded for a US address on November 3, 2026. ridstar.net's own E26 listing showed its only variant sold out that day.

Frequently asked questions

Where can you buy a Ridstar E26?

Three prices stood on November 3, 2026: $1,089.00 for ridstar.com's US variant, in stock; $631.35 on our listing, sold out; and $549.00 for ridstar.net's only variant, sold out. On October 28, 2026, the dealer ridstar-ebike.com listed an E26 and E26 Pro page at $999.00, and ridstar.eu its E26 out of stock.

A $164.70 price from two .it.com sites turned up the same day; the record section weighs it against Ridstar's own statement. For a one-motor 26 × 4.0 bike you can order here, the RS-A08 II was $1,299 that day.

How fast does the Ridstar E26 go?

Ridstar prints "28+++MPH Max Speed" in both stores' bullets and "Max Speed 28 MPH" on ridstar.com's slider; the dealer ridstar-ebike.com prints "30MPH Max Speed".

With 28 mph as the motor's free-running speed, the range model has a 180 lb rider settle at 25.0 mph on flat pavement without pedaling, and at 23.3 mph on a 4% grade, by the motor section. At either figure, the class section finds the E26 outside every US e-bike definition on a throttle.

Is the Ridstar E26 the same bike as the E26 Pro?

No. The E26 has one "1000W Brushless Motor" and a "48V 15.6AH" pack, and Ridstar prints 28 kg for it; the E26 Pro has "two brushless motors with a total power output of 2000W", a "48V 23Ah" pack and "75LBS". The identity section shows how to tell them apart in a photograph: the Pro has a motor in its front hub and a coil shock under the seat.

How far does the Ridstar E26's battery go?

On flat pavement without pedaling, the 748.8 Wh pack carries a 180 lb rider 45 miles at a steady 15 mph and 32 at 20 mph, by the speed tables; keep a quarter back and plan on 34 at 15 mph. Easy pedaling at 15 mph takes the 45 to 70.

Ridstar prints "Max Range 60 Miles" on ridstar.net and "Max Range 45 Miles" on ridstar.com, and the maker-range table turns each figure into the steady speed that delivers it.

How long does a 48V 15Ah e-bike battery last?

On one charge, the E26's 48V 15.6Ah pack runs a 180 lb rider 45 miles at 15 mph on the flat without pedaling, and the cold costs some of that: 36 miles at 32 °F and 32 at 14 °F, by the cold rows. Ridstar prints no cycle life and no charging time for the E26, so ask your seller what the pack's warranty covers in writing.

Is there a Ridstar E26 manual?

Not one Ridstar links. ridstar.com's page titled "Ridstar/YVY User Manual" carries order, return and refund terms and no manual file, and its menu lists the E26 Pro but not the E26; ridstar.net's user-manual address answered "404" on October 28, 2026. Ask your seller for the manual before you buy.

What should you check if a Ridstar E26 is not working?

Start with your seller; each Ridstar store backs only its own orders: ridstar.net "will not provide any after-sales service to customers who purchase ridstar products from other places". On Endless-Sphere, an owner answered a dead throttle on a two-motor E26 Pro with "You do have to be in one of the PAS 1-5 settings, on 0 it will not work".

Leave the controller closed: the E26 page says "Non-professionals please do not adjust the controller circuit！！！". If you bought it here, our refund policy lists both: a bike that "won’t power on" and one that "has a faulty component".

How fast does a 48V 1000W e-bike go?

That depends on the motor's free-running speed and the load as much as on its rating. For the E26, a 48 V bike Ridstar rates at 1,000 W and 28 mph, the range model has a 180 lb rider settle at 25.0 mph on flat pavement without pedaling, and slower on climbs, by the motor section.

Is a 1000W e-bike legal?

No US definition takes it as an e-bike on a throttle at Ridstar's 28 mph: 44 jurisdictions stop the motor at 750 W, and the five others that define one limit a throttle to 20 mph or rule it out. Capped at 20 mph instead, a 1,000 W throttle bike would meet four definitions: the District of Columbia's, Montana's, Oregon's and Rhode Island's, per the state-by-state section.

Is a 1000W e-bike legal in California?

Only outside the e-bike rules: every class in § 312.5 stops at 750 W. On its printed figures it is a § 406(a) motorized bicycle, or moped, through December 31, 2026. On January 1, 2027, SB 1167 starts requiring that class to carry a vehicle identification number and a safety certification label. Ask the DMV before you ride.

Is a 28 mph e-bike legal?

Under California's § 312.5, 28 mph is the class 3 limit, and only for a bike whose motor helps while you pedal and that carries a speedometer. Only class 2 lets the motor move the bike without pedaling, and it stops at 20 mph, so a throttle bike printed at 28 mph is outside all three classes.

Are fat tire bikes better for heavy riders?

A wide tire is not a load rating, and Ridstar prints no load limit for the E26, so no table here goes past 260 lb. On the flat the E26's range falls from 45 miles at 180 lb to 40 at 260 lb at 15 mph, by the weight rows. For a printed limit, Freesky prints "Max Load 400 LBS" for the M-410, and our guide for heavier riders lists more.

Can a fat tire e-bike go in snow?

Ridstar names "snowy suburbs" among the E26's places, on 26 × 4.0 tires, but cold shortens your ride: by the cold rows, a 180 lb rider's 45 miles at 15 mph on a 77 °F day shrink to 36 at 32 °F and to 32 at 14 °F. Ridstar gives no tire pressure for the E26; our fat tire guide opens with three picks for sand, snow and trail riding.

Is the Ridstar E26 good for tall riders?

Ridstar's window runs to 6'3", but its top saddle setting, 98 cm from the ground, is short of 109% of any inseam over 35.4 inches. At 6'1" the Army survey's median inseam is 35.6 inches, so it falls short for 55 riders in 100 at 6'1", 74 at 6'2" and 86 at 6'3" (the fit section). If that is you, our tall-rider guide matches bikes we sell to taller bodies.

Is the Ridstar E26 full suspension?

Ridstar's text says so, "Suspension Type Front，Rear" on ridstar.net and a "Rear Shock Absorber" on ridstar.com, but every Ridstar photograph of the whole E26 shows a suspension fork and a rear triangle with no shock, by the frame section. For a 26 × 4.0 bike whose maker prints a rear shock, see the RS-A08 II.

Is a fat tire e-bike better than a regular one?

It depends on where you ride. On pavement the model rolls the E26 on the median of ten drum-measured 26 × 4.0 fat tires, a coefficient of 0.0105, by the tire subsection, and Ridstar lists the E26's uses as "Downtown around, rocky roads, sandy beaches, snowy suburbs, and even urban jungles". Our fat tire versus regular tire guide sets the two side by side.

What are the best fat tire electric bikes?

That depends on you and the job. Of the 26 × 4.0 bikes in stock here, the RS-A08 II carries a shock at each end, the STORM a 960 Wh pack on one motor, and the M-410 two motors; our fat tire guide sets twelve picks against seven kinds of ride.

Limitations of this review

Twenty-four limits follow: what the published record leaves out, and what the models assume in its place.

1. Where Ridstar's figures compete, this page prints them side by side. Motor 1,000 W and 2,000 W, with a dealer's 1,500 W peak; pack 15.6 Ah and 14 Ah; range 60, 45 and 25 to 70 miles; top speed 28 mph, with dealers' 30 mph and 45 km/h; warranty one year and two.
2. No load limit is printed by either Ridstar store or by its dealers ridstar.eu and ridstar-ebike.com, so the rider rows stop at 260 lb.
3. Ridstar prints no torque for the E26, so the comparable motor's 90 N·m stands in as the ceiling.
4. The motor curve is a comparable's. Bafang's RM G0H0 supplies that curve, scaled to 48 V and 1,000 W, and Ridstar's 28 mph sets the speed the motor would spin to unloaded. From the dealer's 30 mph instead, a 180 lb rider's flat top speed would be 26.3 mph rather than 25.0.
5. The rating is the bullets' 1,000 W. Across the four cases, 1,000 W, 750 W, the Technical Details' 2,000 W and 82% efficiency, the 15 mph flat ride runs 42 to 49 miles.
6. No controller current is printed. A controller that caps current would hold the steepest climbs below the model's speeds; a 15% grade at 10 mph draws 47.6 A from the pack.
7. No wheel diameter is printed for the E26. The model uses 29.9 inches, Ridstar's printed figure for the same 26 × 4.0 tire on the E26 Pro, and that number changes only the torque a climb needs.
8. No drum test covers the CHAOYANG tire on Ridstar's drawing, so the model uses the median of ten measured fat tires, brackets it with the easiest and the heaviest, and stays on pavement.
9. The cold rows rest on one cell's published data, LG's HG2, because neither E26 page names the pack's cells or their format.
10. No measured E26 ride is on record to check the model against: no owner account names the one-motor E26 with a rider weight, a speed and a distance.
11. No E26 page names a throttle. The range tables run on the motor alone, and the class section is read both with a throttle, which Ridstar's parts store sells for the E26, and without one.
12. The two seat heights are Ridstar's drawing's, printed in centimeters only, and the drawing's lengths did not agree with one another within 3.5% at any one scale, so nothing else was measured from it.
13. The seat figures are one-sided bounds, since Ridstar's E26 pages give no grip position, reach, standover, crank length or pedal height; for the same reason the lean and the hand load are left uncomputed.
14. Soldiers make up all 6,068 ANSUR II bodies, so the counts describe an army's spread of heights and legs, and a height with fewer than 30 bodies gets no row.
15. Saddle formulas are averages. Between them, the 106% and 110.4% formulas leave a 5'8" rider a 1.4-inch saddle window; the heel check on your own leg is what settles the point inside it.
16. LeMond's 88.3% is not checked against the 109%, because that needs a crank length, which no E26 page prints.
17. Ridstar's text and photographs disagree on the rear suspension, and this page cannot say which a given bike will have.
18. "Dual Battery" is not explained on any E26 page, and the box on the top tube carries no label.
19. No document we found links the E26 to a UL certificate, and Ridstar claims none; the footer files are two trademark registrations and an EN 15194 report on another model.
20. One listing for two bikes' parts does not make the parts one. Where an E26 option sits beside a Q20 or E26 Pro option on one listing, Ridstar never says whether the parts match, and the E26 is in no warning, report or suit.
21. The owner record for the one-motor E26 is empty on Ridstar's pages, and the forum posts that name an "E26" concern the E26 Pro or do not say which; walmart.com's listings, where an AI search summary placed a buyer's review of a Ridstar E26, turned away automated reads on October 28, 2026, so that review is unread here.
22. The dealer record is partial. ridstar.uk answered "404", and two more .it.com storefronts, beside the two quoted in the record section, did not answer on October 28, 2026; the dealers that did were read once.
23. Every state result is drawn from a single 51-row rule table, with a statute link on each row. On November 3, 2026, the federal, California, Oregon, District of Columbia, Montana and Rhode Island texts were read again; New Jersey's publisher did not answer that day, so its law was read in the Wayback Machine's copy of August 22, 2026.
24. One national rate prices every cost on this page, the EIA's 18.16 cents per kWh for August 2026, with the charger's own losses left out; a different utility rate scales each figure up or down.

The bottom line

The E26 is worth buying if a one-motor fat-tire bike on 26 × 4.0 tires, with a steel frame, 748.8 Wh and a rack, suits a rider about 5'8" to 6'0", and your seller will put the motor rating, the pack, the brakes, the charger and the rear suspension in writing.

A full charge, by the model, takes a 180 lb rider 45 miles at a steady 15 mph on level pavement without pedaling. Before you pay, read the maker's record, and get the charger and every front-wheel part named in writing.

On November 3, 2026, ours was sold out and ridstar.com had the E26 at $1,089.00. If you want to order today, start with the RS-A08 II at $1,299, a shock at each end; for a bigger pack, the STORM at $1,299; at the E26's price, the DK400 at $665; and for printed certifications and a load limit, the M-410 at $1,299.

Photographs: after the cover come ten images from Ridstar's own E26 files on ridstar.net and ridstar.com: two studio views, four crops at native size, the cockpit evenly scaled, the headlight, the taillight and the "SIZE" drawing, none retouched.

Cover: Ridstar's studio photograph of the gray E26, the lead image on its ridstar.net listing, placed at one even scale and otherwise unaltered, on a charcoal studio that Nano Banana Pro on Playcut generated for an earlier cover of ours, reused without change. We added the soft shadows under the two tires, drawn from the shadow in Ridstar's own frame, and set the type and the badge.

Expiry conditions

This review is due a fresh pass when the E26 is back in stock here, or when ridstar.net or ridstar.com changes its stock, price or figures for the E26; when the CPSC recalls a Ridstar or YVY bike, or issues or amends a warning; and when the October 23 order in L.E. v. Walmart can be read or either suit reaches a judgment.

It is due again on January 1, 2027, when California's SB 1167 takes effect; when our own prices, stock, listing text or store policies change; when 15 U.S.C. § 2085, California Vehicle Code §§ 312.5, 406 or 21207.5, or any state's e-bike definition changes; and when Samebike, Smartravel, Freesky or Ridstar publish new figures for the RS-A08 II, the STORM, the DK400, the M-410 or the E26.
